TS Adapter for recessed adaptation of correctors in the focuser UNCN3M82 The TS V-Power focuser with the M82 threaded connection on the camera side accepts large correctors up to 3" body diameter. This adapter allows correctors to be connected via the M68x1 male thread on the corrector. The corrector is recessed into the draw tube, saving valuable optical path. Tilting, as is possible with clamping, is eliminated by the screw connection. On the camera side, the adapter has an M48x0.75 male thread for further adaptations. How the adapter works and what to consider: ♦ Screw the corrector into the M68x1 female thread of the adapter. ♦ Then screw the adapter with the corrector into the M82x1 female thread of the focuser. ♦ Please consider that the adapter needs 9 mm travel (length of the M68x1 female thread and overall length of the adapter) - these 9 mm must be subtracted from the working distance of the corrector. The advantage is that all larger correctors offer a longer working distance. Application example: TSKORW3 on a 325 mm f/4 Newtonian with this adapter: ♦ working distance of the KORW3 Wynne corrector is 64 mm ♦ 9 mm optical path to be subtracted - so 55 mm remain from the M48x0.75 male thread on the adapter. Ideal therefore for all photo adaptations ♦ The exact working distance can be established with suitable adaptations and tuning rings.
